High-performance non-contact speed sensors
With excellent low speed measurement capabilities, increased beam width, built-in tilt compensation, rain interference discrimination and low power consumption, Modbus RTU output, LONG RANGE MICROFLOW (LRMFLOW) is the right choice for clean water, wastewater, industrial or irrigation applications.
Tried and tested
Designed specifically with harsh global weather conditions in mind, the LONG RANGE MICROFLOW speed sensor has been tried and tested in a wide range of climatic conditions, including tropical storms. Without loss of data, LONG RANGE MICROFLOW provided repeatable and accurate results thanks to its more powerful signal processing and rainfall discrimination system.
Easy to install and use
The need for installation skills and resources is minimised thanks to the integrated tilt sensor that automatically mitigates user error in the installation angle. With standard Modbus RTU output, LONG RANGE MICROFLOW is compatible with both third-party RTUs or loggers, as well as our dedicated electronics. LONG RANGE MICROFLOW can be used with continuous or intermittent power supply to reduce power consumption when connected to a logger.
Advanced measurement capabilities
LONG RANGE MICROFLOW can be mounted up to 15 metres above the water surface, making it ideal for applications where the mounting position cannot be changed, such as the flow of a river under a bridge. The measuring area of the sensor can be up to 3 metres, which means that fewer sensors are needed to measure speed over wider channels. LONG RANGE MICROFLOW is the right choice for applications with varying flow rates due to its ability to measure velocities up to 0.2 metres per second.
